The figures are from Heroscape and we use them as Not-Predators. The Harrakians are basically not heavily armored, favoring camouflage rather than armor. This is shown by the Active Chameleon tech that basically allows them to always be treated as having moderate cover. The roll needed to hit the Harrakian is modified by +2, which is quite difficult. I guess that's a pretty fair trade for having minimal armor. Plus, they have a devastating 4 volleys of 5 FP per figure that can target units as per the guided munitions rules from FUBAR's sci fi supplement. Let me know if you use the stats and how they work out for your game. A 4 man squad of these guys decimated 4 squads of troopers in a recent game!
